Cost at 50, 200 and 1,000 Winnr mailboxes
Winnr recommends 10 to 20 cold emails per mailbox per day (15 by default) and up to 50 in total including warming. At 15 a day, Winnr's 50, 200 and 1,000 mailboxes send 750, 3,000 and 15,000 cold emails a day. Here is Mailreef Agency Flex at the same cold volume, using its calculator's method (servers = monthly sends ÷ 100,000, rounded up; plus $0.001 per send; 30-day month). Example for 3,000 a day: 90,000 sends = 1 server ($249) + $90 = $339.
| Winnr mailboxes (cold emails/day) | Winnr | Mailreef Agency Flex |
|---|---|---|
| 50 (750/day, 22,500/mo) | $69 (Startup) | $271.50 (1 server $249 + $22.50) |
| 200 (3,000/day, 90,000/mo) | $189 (Enterprise) | $339 (1 server $249 + $90) |
| 1,000 (15,000/day, 450,000/mo) | $989 (Enterprise $189 + 800 × $1) | $1,695 (5 servers $1,245 + $450) |
At Mailreef's guidance of about 25 cold emails per mailbox per day, the same volumes need roughly 30, 120 and 600 Mailreef mailboxes. Mailreef does not charge per mailbox, so mailbox count does not change its price. Its calculator charges for campaign sends; check with Mailreef whether warm-up traffic is billed the same way.
Monthly cost per 1,000 daily cold sends
| Cold emails per day | Winnr | Mailreef Agency Flex |
|---|---|---|
| 750 | $69 ÷ 0.75 = $92.00 | $271.50 ÷ 0.75 = $362.00 |
| 3,000 | $189 ÷ 3 = $63.00 | $339 ÷ 3 = $113.00 |
| 15,000 | $989 ÷ 15 = $65.93 | $1,695 ÷ 15 = $113.00 |
Mailreef's fixed $249 server fee makes it expensive at low volume; above about 100,000 sends a month its cost settles near $113 per 1,000 daily sends (about $3.77 per 1,000 emails), against roughly $63 to $66 on Winnr ($2.10 to $2.20 per 1,000 emails).
Mailreef includes a dedicated IP with each server. On Winnr a dedicated IP is $20 a month on Enterprise, so 3,000 cold emails a day with one dedicated IP is $189 + $20 = $209, against $339 on Mailreef. See when a dedicated IP is worth it.
